create brand logos, tag lines and labels

We are a cleaning products company with three brands. For our top quality brand we have a logo already. This is a brand of high quality performance and innovative products for the cleaning industry. This could be cleaning chemicals, tissue paper products, machines, janitorial supplies, etc. We would like you to suggest tag lines for the brand and figure out how to incorporate that into our existing logo or perhaps change the logo. The second brand is a mid-range of cleaning chemicals. The products are reliable and effective. We need a logo and tag line for this brand. Third is our economical / affordable brand of cleaning chemicals. These are standard quality products. And we need a logo and tag line for these as well. All three logos/taglines will need to be printed on paper/plastic sticker labels to be put on the products. Part of the assignment is to create the label design in one size with 6 different colours. It will be pretty much the same design for each brand, just with different colours. And here again we need your input on whether the logo colour needs to change or only some elements of the label need to clearly reflect the colour. These labels could also have borders of the colours and white inner box to input product information text. Label size 13cm x 13cm. The 6 colours are: Purple Pink Yellow Green Blue Red
